Specification of Letters Patent.

Patented Sept. 10, 1907.

Application filed September 17, 1906. Serial No. 334,915.

To all whom it may concern:

Be it known that I; JASPER H. STANFIELD, a citizen of the United States,residing at Muskegon, in the county of Muskegon and State of Michigan,have invented certain new and useful Improvements in MechanicalMovements; and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to improvements in mechanical movements.

The object of the invention is to provide a mechanical movement, wherebya reciprocating and an oscillating motion is simultaneously imparted toa shaft.

With the above and other objects in view, the invention consists ofcertain novel features of construction, combination'and arrangement ofparts, as will be hereinafter described and claimed.

In the accompanying drawingsi-Figur'e l? is aside elevation, partly insection, showing the construction and arrangement of the invention; Fig.2-is an end view of the same; Fig. 3 is a vertical sectional view on theline 33'of Fig. 1; and Fig. 4 is a detail perspective view of the togglecrank on the operating shaft.

The mechanical movement herein shown and described is particularlyadapted for use in connection with washing machines or other machineswherein both a reciprocating and oscillating movement is desired andconsists of a driving or operating shaft 1 mounted in a suitable frame 2adapted to be secured to the body of the machine.

The outer end of the shaft 1 is reduced and threaded, as at 3, and isalso provided with a squared or flattened side 4. On the outer end ofthe shaft 1 is mounted a crank handle 5, the head of which is bored tocorrespond to the reduced and flattened end of the shaft. The handle 5is secured on said end of the shaft by a thumb screw 6, which is screwedonto the projecting threaded end of the shaft. On the opposite end ofthe shaft 1 is secured a fixed head 7, the outer end of which isflattened and on said flattened end of the head is pivotally mounted alink 8, the inner enlarged end of which is bifurcated to receive theflattened portion of the head 7 In the outer end of the link 8, whichconstitutes a motion transmitting element or member, is formed a hole orsocket 9, with which is adapted to be engaged the spherical-headed end10 of a wrist pin 11 secured to and projecting laterally from a drivenshaft 12 whereby when the shaft 1 is operated the shaft 12 will besimultaneously reciprocated and oscillated. The head 10 of the pin 11 isheld in the aperture or socket 9 in the link, by means of a lip orflange 13.

Keyed or otherwise fixedly mounted on the shaft 1 midway between theends of the same is a gear wheel .14, which is engaged by a pinion 15mounted on one end of a counter shaft 16 journaled in asleeve 17, whichis formed integral with gear casings l8 and 19 connected to thesupporting frame Said casings also have formed integral therewith abearing sleeve 20, in which the intermediate portion of the shaft l isjournaled. On the other end of the counter shaft 16 is fixedly mounted agear 'wheel 21, which is adapted to mesh with gear teeth 22 formed onthe hub of a fly wheel 23, which is loosely mounted on the shaft 1adjacent to the crank handle 5, the gear-toothed hubconstitutingapinion. The hub of the fly wheel 23 is provided with bearing rollerstoengage the shaft 1, so that said fly wheel will turn freely thereon.

By connecting the fly wheel 23 with the drive shaft 1 as herein shownand described power will be transmitted from the shaft 1 back to the flywheel, which will be driven thereby at an increased speed. Said speedwill be determined by the ratio of the gears connecting the fly wheelwith the shaft. The object of connecting and driving the fly wheel inthis manner is to provide a velocity for the same, whichwill impart tothe whole machine a steady and uniform motion.

'From the foregoing description, taken in connection with theaccompanying drawings, the construction and operation of the inventionwill be readily understood without requiring a more extendedexplanation.

- Various changesin the form, proportion and the minor details ofconstruction may be resorted to without i 1. A mechanical motionembodying a shaft, .8. pivoted motion transmitting member carriedthereby, a fly wheel loose on the shaft, and a train of gears to connectthe shaft and the wheel.

'2] A mechanical motion embodying a\shaft, a motion transmitting membercarried thereby, a fly wheel loose on the shaft, a pinion carried by thefly wheel, a gear fixed on the shaft, a counter-shaft, a pinion fixed onthe countershaft to mesh with the gear, and a gear also fixed on thecounter-shaft to mesh with the fly wheel pinion.

3. A mechanical motion embodying a driving shaft and a'driven shaft,means for transmitting motion from the driving to the driven shaft, 11fly wheel loose on the driving shaft, and a train of gears to connectthe latter shntt and the wheel 4. A mechanical motion embodying adriving and a 5 driven shaft, 51 wristpin carried by the driven shaft,3. link pivoted to the driving shaft and engaging the wristpin, a flywheel loose on the shaft, and a train of gears to connect the shaft andthe wheel.

5. A mechanical motion embodying a driving and a 10 driven shaft, a ballheaded wristpin carried by the driven shaft, 2. link pivoted to thedriving shaft and having a socket to be engaged by the ball head of thewristpin, a fly wheel loose on the shaft, and a train of gears toconnect the shaft'and the wheel.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.

A JASPER H. STANFIELD.
